Hello,
Can you please try this code in sale.order object:

@api.onchange('partner_invoice_id')
def onchange_partner_invoice_id(self):
    if self.partner_id:
        invoice_partner_ids = self.env['res.partner'].search([('id', 'child_of', self.partner_id.id)])
        return {'domain': {'partner_invoice_id': [('type', '=', 'invoice'), ('id', 'in', invoice_partner_ids.ids)]}}

@api.onchange('partner_shipping_id')
def onchange_partner_shipping_id(self):
    if self.partner_id:
        delivery_partner_ids = self.env['res.partner'].search([('id', 'child_of', self.partner_id.id)])
        return {'domain': {'partner_shipping_id': [('type', '=', 'delivery'), ('id', 'in', delivery_partner_ids.ids)]}}
